"Monitoring by the ministry has so far found no criminal elements, recruitment or fund collection for terrorism activities in the application (Telegram)", he said after attending a Hari Raya open house event at Jakel Mall, here today.
"We respect the rights of individuals to use social media, but we also need to use decoding methods to determine if there are elements of terrorism - like the Islamic State - whether online, on social media, or offline", he said.
If a social media platform does not comply with the government's rules, the government would initially limit the advertisements that appear on the platform, hurting their business potential in the country.
The ministry on Friday said it was preparing for a total closure of Telegram in Indonesia if it did not develop procedures to block unlawful content.
The 11 blocked Telegram domain name systems (DNS) are t.me, telegram.me, telegram.org, core.telegram.org, desktop.telegram.org, macos.telegram.org, web.telegram.org, venus.web.telegram.org, pluto.web.telegram.org, flora.web.telegram.org and flora-1.web.telegram.org, according to the Jakarta Post.
Telegram is a free Russian-designed messaging app that lets people exchange messages, photos and videos in groups of up to 5,000.
It is also the highest messaging app in Iran with 40 million active users as of April this year.
Telegram is primarily distinguished from its competitors, such as Whatsapp, by its security features including secret chat rooms and self-destructing messages.
It is reported that Islamic State had recommended the messaging service to its members and sympathisers, with over 9,000 followers on its official channel by October 2015.
On Saturday, communications minister Rudiantara said that Telegram had not processed the government's requests to take down "radical" content quickly enough.
The address came following an abrupt limiting of messaging service Telegram late last week.
Together, the ministry and Telegram have devised a three-step plan to resolve the issue: blocking all "terrorist-related" channels requested by the ministry, establishing direct communications between the CEO and the ministry and forming an Indonesian-language team of moderators to focus on terror material originating from or targeting the region.
